# Domain error (input argument is outside the range in which the operation is mathematically defined, e.g. std::sqrt(-1), std::log(-1), or std::acos(2)). If MATH_ERRNO bit is set, EDOM is assigned to errno. If MATH_ERREXCEPT bit is set, FE_INVALID is raised.

# Overflow (the mathematical result is finite, but too big to be represented without extreme roundoff error, e.g. functions such as std::exp with sufficiently large arguments). If MATH_ERRNO bit is set, ERANGE is assigned to errno. If MATH_ERREXCEPT bit is set, FE_OVERFLOW is raised.

# Underflow (the mathematical result is non-zero, but too small to be represented without extreme roundoff error, e.g. the result is subnormal, as in std::sin(subnormal) or for many other functions with subnormal arguments). If MATH_ERRNO bit is set, ERANGE may be assigned to errno. If MATH_ERREXCEPT bit is set, FE_UNDERFLOW may be raised.
